Remarks

Report an accessibility action to this view's parents for delegated processing.

Implementations of #performAccessibilityAction(int, Bundle) may internally call this method to delegate an accessibility action to a supporting parent. If the parent returns true from its ViewParent#onNestedPrePerformAccessibilityAction(View, int, android.os.Bundle) method this method will return true to signify that the action was consumed.

This method is useful for implementing nested scrolling child views. If #isNestedScrollingEnabled() returns true and the action is a scrolling action a custom view implementation may invoke this method to allow a parent to consume the scroll first. If this method returns true the custom view should skip its own scrolling behavior.
